Position Descriptions for Students to Apply For

 

Faculty Name & Department/School: Dr. Virginia Weis: Department of Zoology

 

Research Project Title: Understanding coral-algal symbioses

 

Project Overview: 

Corals are the cornerstone of an entire ecosystem and can build stone structures that can be seen from space! Their success is largely dependent upon a beneficial symbiosis with a marine algae called Symbiodinium. There are many types of Symbiodinium available on a coral reef, but corals are able to find one, or a few, strain(s) that fit them best. To help understand why they are so selective, this project will utilize the sea anemone Aiptasia as a model. Different strains of Symbiodinium will be used to inoculate separate anemone clones to determine differences in the host’s growth and reproduction.

 

What skills will students obtain in this project? 

Students will learn basic molecular biology skills such as DNA extraction and amplification. Students will learn how to genetically identify Symbiodinium strains and how to generate, interpret, and utilize DNA sequence data. Basic microscopy, cell counts and potentially histology will be taught to visualize Symbiodinium. Students will also be introduced to culturing of algae and husbandry of marine animals.

 

Student research tasks: 

The student will extract DNA from cultured Symbiodinium isolated from many different coral hosts and amplify several different genes to find genetic differences. He/She will then inoculate cultures into non-symbiotic anemones and follow the progression of infection macro- and microscopically. The student will assess growth, Symbiodinium density within the host, and asexual (clonal) reproduction of the anemone.
